[PATCH v2 8/8] riscv: mm: Add support for ZONE_DEVICE

From: Björn Töpel ZONE_DEVICE pages need DEVMAP PTEs support to function (ARCH_HAS_PTE_DEVMAP). Claim another RSW (reserved for software) bit in the PTE for DEVMAP mark, add the corresponding helpers, and enable ARCH_HAS_PTE_DEVMAP for riscv64. Signed-off-by: Björn Töpel ---
